I think S&T and most of the others are designed primarily for relatlively simple route planning, i.e., going from home to Grandma's house with maybe a stop at the antique shop and the outlet mall. (I know they do lots of other things but not very well and not always very easily.) People like JesseJames have a genuine need for certain features but his needs are different from mine and mine are different from John Doe's and John Doe's are different from....... There are so many different possibilities that it probably ain't gonna happen.
